Descriptions

lxclock.c in LXC 1.1.2 and earlier allows local users to create arbitrary files via a symlink attack on /run/lock/lxc/*.

Vulnerabilidad en lxclock.c en LXC 1.1.2 y versiones anteriores, permite a usuarios locales crear archivos arbitrarios a través de un ataque symlink en /run/lock/lxc/*.

Roman Fiedler discovered that LXC had a directory traversal flaw when creating lock files. A local attacker could exploit this flaw to create an arbitrary file as the root user. Roman Fiedler discovered that LXC incorrectly trusted the container's proc filesystem to set up AppArmor profile changes and SELinux domain transitions. A local attacker could exploit this flaw to run programs inside the container that are not confined by AppArmor or SELinux. Various other issues were also addressed.
